The point you want is (0,-2)
The slope of that line would be (4-(-2))/(-1-0)= -6
the line would be y= -6x-2
Answer:
r = (3V/π)^1/3
Step-by-step explanation:
Given that :
Volume of a sphere = V = 4/3πr³
Dividing into 4
4/3 * 1/4 πr³ = 4/12πr³ = 1/3πr³
V = 1/3πr³
Cross multiply
3V = πr³
Divide both sides by π
3V/ π = πr³/ π
3V/ π = r³
Take the cube root of both sides
r = (3V/π)^1/3
Answer 1
She should put 7 students in each group. And there will be 4 groups.
Answer 2
She should put 4 students in each group and there will be 7 groups.
Explanation: 7*4 =28
Solve for x in the second equation.
Just add 1 to both sides to get x = 9y + 1
Then plug 9y + 1 into the first equation for x
7(9y+1) - 9y = 1
63y + 7 - 9y = 1
54y + 7 = 1
54y = -6
y = -6/54 or -1/9
Plug y back into one of the equations to get x = 0
Answer: (0, -1/9)
Answer:
n - 6
Step-by-step explanation:
Firsly, break the bracket and you will get:
-2(n+3)+3n
= -2 * n + 3 * (-2) + 3n
= -2n + (-6) + 3n
= -2n + 3n - 6
= n - 6
Hope this helped :3
